Why are lower layers in archaeological excavation generally considered older?
Answer and explanation
Correct answer: Because newer layers settle above over time
The principle of stratigraphy states that, in an undisturbed sequence, deposits formed earlier generally lie below deposits formed later. Soil, construction debris, waste, and flood deposits can accumulate over time, placing newer material above older material. This is a general rule, not an absolute one: digging, erosion, burrowing, or later construction may disturb layers, so archaeologists examine context carefully rather than relying on depth alone.
